8 Packaging

Pallets with Paper Bags Big bags HDK® is available in multilayer valved The big bag solution is available for most paper bags which contain 10 kg of HDK® grades, a woven polypropylene product. The bags are delivered on bag containing 150–200 kg of product, pallets which are shrink-wrapped with depending on the respective bulk density a polyethylene foil to protect the HDK® of the product. Big bags are delivered against moisture. This allows the on a pallet shrink-wrapped with a poly- product to be stored without any ethylene film to protect against moisture. moisture uptake. If the shrink foil is damaged or single bags are removed, care must be taken to protect the remaining bags/individual bags against moisture by either wrapping in plastic or other appropriate measures.

• Palletized and shrink-wrapped for good product protection, storage and handling • Three-ply paper for added strength • Bags are disposable
